Aortic Valve Replacement and Concomitant Coronary Artery Bypass: Assessing the Impact of Multiple Grafts Kimiyoshi J. Kobayashi, BS, Jason A. Williams, MD, Lois Nwakanma, MD, Vincent L. Gott, MD, William A. Baumgartner, MD, John V. Conte, MD The Annals of Thoracic Surgery Volume 83, Issue 3, Pages 969-978 (March 2007) DOI: 10.1016/j.athoracsur.2006.10.027 Copyright © 2007 The Society of Thoracic Surgeons Terms and Conditions

Fig 1 Cumulative late survival of completely and incompletely revascularized aortic valve replacement and coronary artery bypass grafting (AVR-CABG) patients. (*p value compared the difference between the cumulative survival of those patients who were completely and incompletely revascularized at the time of AVR-CABG over the entire five-year study period, excluding those patients who were considered operative mortalities). (— = completely revascularized; – – – = incompletely revascularized.)

Fig 2 Postoperative improvement in New York Heart Association (NYHA) class. For (A) there were 15 patients for whom we lacked adequate information to assign NYHA functional status. For (B) and (C) there were 11 and 15 patients, respectively, for whom we had inadequate postoperative information. (*p values compared the number of preoperative and postoperative patients who were class III/IV; p < 0.001 for the first three patient groups [one, two, and multiple bypass grafts]).

Fig 3 Freedom from repeat revascularization. (*p value compared the difference between the overall rate of freedom from repeat revascularization among the three patient groups over the entire five-year study period, excluding those patients who were considered operative mortalities). (— = one graft; – – – = two grafts; - - - - - = multiple grafts.)

Fig 4 Cumulative survival of aortic valve replacement and coronary artery bypass grafting patients stratified by the number of bypass grafts. (*p value compared the difference between the overall cumulative survival among the three patient groups over the entire five-year study period, excluding those patients who were considered operative mortalities).
